Atub containing 58 kg of water is placed in a farmer's canning cellar, initially at 15 ∘c. on a cold evening the cellar loses thermal energy through the walls at a rate of 1200j/s. without the tub of water, the fruit would freeze in 4 h (the fruit freezes at −1 ∘c because the sugar in the fruit lowers the freezing temperature).

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
